M4 Tool Steel Machinability

The grade has an excellent balance of toughness and wear resistance making it ideal for cutting tools and for cold work tooling. M4 high speed tool steel m4 is a molybdenum tungsten high speed steel that is characterized by its high abrasion wear resistance transverse bend strength and impact toughness. Pm m4 is a molybdenum tungsten high speed steel produced using the pm powdered metal steel making process.

High Speed Steel An Overview Sciencedirect Topics

There are four principal benefits of cpm high speed steels for tool users.

M4 tool steel machinability.

Cpm rex m4 hc powder metal high speed steel. The high impact toughness and high transverse bend strength are results of the fine grain. This specialty high speed steel was developed to have a greater abrasion and wear resistance for high tool life quality and cutting speeds. Form tools hobs milling cutters etc the trend is toward upgrading to cpm m4 which is the toughest high speed steel we produce and is surpassed in wear resistance only by cpm t15.

Heat treatment m4 steels can be preheated at 788 c 1450 f and then rapidly heated to 1218 c 2224 f for 3 5 minutes followed by oil salt bath or air quenching process. A large volume of vanadium carbides provides the high wear resistance. Sbsm high speed steel properties comparison. Pm steels have excellent grindability vs conventional steels.

Better annealed machinability b more consistent and safer heat treat response. Cpm rex m4 hc high speed steel is an extremely versatile high speed steel that provides a unique combination of high wear resistance with high impact toughness and transverse bend strength. The machinability of m4 steels is comparatively low rating about 40 than that of water hardening tool steels which are much easier to machine. It is well suited for premium cutting tools of all types particularly those used for machining abrasive alloys castings and heat treated materials.

M4 is an extremely versatile high speed steel with its extremely high carbon and vanadium contents for exceptional abrasion resistance.
